Hey guys, a little question for the people that have gone through some building here. I wan to do concrete flooring and i wanted to see what your experiences is here. My builders (as always) just say "bisah bisah" but i am pretty sure they havent done this before. What do i need to know about mixture proportion, application technique or protection from humidity? Any other concrete lovers here to put me on the right path? And while we are at it, you have a contact to someone that can do good work with aluminium windows in the Ubud area? Thanks guys!
